Pipeline RehabilitationWithin the APS Pipeline Rehabilitation Division we are able to provide turnkey service to our customers in the utility, power, oil and gas industries. The choice of the most suitable pipeline rehabilitation system depends upon which performance parameters the pipe fails to meet and why the failures occur. Criteria like; condition of the existing pipeline, requirements for the desired performance, hydraulic capacity and structural design data, as well as �nancial considerations have to be taken into account. Since there is no single solution that covers each and every pipeline rehabilitation project, APS prides itself in providing a very broad range of pipeline rehabilitation methods from which we can o�er a tailor-made solution �tting the speci�c circumstances of the project. Danby Panel Lok is one of these solutions.

Municipal providers all over the world face problems with their pipe infrastructures. Sewer and storm water pipes all su�er from age and deterioration, which can result in severe pipe damage. The high costs and impact on the local community often make it di�cult to renew the underground infrastructure with the traditional open-trench methods. With the Danby Panel Lok System, rehabilitation of pipes is conducted intelligently and e�ciently without requiring digging or pits, thus avoiding a severe inconvenience to urban life.

The Danby Panel Lok system for pipeline rehabilitation is both low-impact and cost-e�cient, which makes it particularly useful in metropolitan areas. The Danby Pipe Rehabilitation process is a classic case of where the sum is greater than its parts. Danby's Rigid PVC strips, or panels, provide corrosion protection and improved �ow characteristics. They also serve as the “form" that contains the grout. The cementitious grout, in turn, provides the anchoring system and structural strength.

Installation Guidance Danby Panel Lok1) For circular or near circular structures, Danby is

typically extruded in coils of 50 meter lengths, then delivered to the job site.

2) After the deteriorated structure has been cleaned and prepped, Danby strips are manually unspooled and lowered through a manhole and put into place in continuous lengths. Once inside the pipe, the PVC panels are joined by incorporating male and corresponding female double locking edges. These edges form a circumferential joint which is then locked together using a smaller joiner strip made with an elastomer gasket, co-extruded to ensure the seams and joints are both gas and water tight.

3) Grout is then injected into the annular space from multiple injection points. Although any grout material, ranging from high strength cementitious materials to light-weight foam can be injected without undue restrictions due to �ow characteristics, typically a mixture of OPC and Fly Ash is used forming a low viscosity, rapid setting high strength grout which provides additional structural strength.

4) When complete, the newly relined pipe is more structurally sound, with greater hydraulic �ow characteristics than the original.

Danby Panel Lok System TechnologyThe Danby System is a so-called Grouted-In-Place Liner (GIPL) and is manufactured in-situ with corrosion resistant plastic. Its primary components consist of extruded 300 mm wide, rigid PVC strips that are manufactured in pro�le heights of 12MM and 25MM. The Danby outer surface is ribbed, while the inside surface is smooth. The ribs, when curved to the contours of the host pipe, impart a hoop strength that provides the support to hold the liner in place and resist the grout pressure. The ribs also become the mechanical anchor when it bonds to the grout that is injected to �ll the annular gap. The grout provides critical structural enhancement. The Danby System will extend the rehabilitated pipeline’s useful life by another 50 to 100 years.

The Danby Panel Lok system is meeting the ASTM F1698-02; Standard Practice for Installation of Poly Vinyl Chlor ide (PVC ) Pro�le str ip L iner and Cementitious Grout for Rehabilitation of Existing Man-Entry Sewers and Conduits; and the ASTM F1735-02 (Re-approved 2008);

Standard Speci�cation for Poly Vinyl Chloride (PVC) Pro�le Strip for PVC Liners for Rehabilitation of Existing Man-Entry Sewers and Conduits.
